Tomahawk not playing sound

Hi, Tomahawk opens well, all seems to function good, play button works, i see slider progressing but i hear no sound .
I use computer daily with lots of other apps, all have sound.

When i start tomahawk, and enter sound settings and click applications i see message:

No application is currently playing or recording audio

I love the look of Tomahawk and would very much like to use it, so advices are welcome :slight_smile:

greetings!!!
